[0009] Preferably, the support ring is installed on the tape cutter mounting tube and fixed by a mounting buckle.

[0010] Preferably, the raised surface of the handshake block fits the palm of the hand.

[0011] Working principle: When the tape cutter is in use, the user holds the hand gripper, and the palm of the user's hand fits against the gripping block. The user's index finger, middle finger and ring finger correspond to the undulations on the surface of the reinforcing block and the connecting piece respectively. The tape is installed on the outer surface of the installation body, and the inner gear ring is engaged with the elastic teeth on the limiting ring, which plays a role in unidirectionally controlling the unidirectional movement of the tape installed on the outer surface of the installation body.

[0012] The present invention provides a hand-held device for an anti-falling adhesive tape cutter, which has the following beneficial effects:

[0013] The support ring on the mounting body of the present invention is mounted on the inner side of the tape mounting tube of the tape cutter, and is fixed by an elastic buckle. The protrusions provided on the mounting ring are tightly matched with the tape to prevent the tape from falling off. The surface of the handgrip block is raised, and the raised part fits the palm of the user. The mounting buckle and the surface of the connecting piece also have high and low undulations that fit the fingers of the user, so that the handgrip fits the hand of the user and is comfortable to use.
